Since for Ago. "He came here not long since and died."
Smart for Bright, or Able. An Americanism that is dying out. But "smart" has recently come into use for fashionable, which is almost as bad.
Snap for Period (of time) or Spell. "A cold snap." This is a word of incomprehensible origin in that sense; we can know only that its parents were not respectable. "Spell" is itself not very well-born.
So—as. See As—as.
So for True. "If you see it in the Daily Livercomplaint it is so." "Is that so?" Colloquial and worse.
Solemnize. This word rightly means to make solemn, not to perform, or celebrate, ceremoniously something already solemn, as a marriage, or a mass. We have no exact synonym, but this explains, rather than justifies, its use.
Some for Somewhat. "He was hurt some."
Soon for Willingly. "I would as soon go as stay." "That soldier would sooner eat than fight." Say, rather eat.
Space for Period. "A long space of time." Space is so different a thing from time that the two do not go well together.
Spend for Pass. "We shall spend the summer in Europe." Spend denotes a voluntary relinquishment, but time goes from us against our will.
